Title: Improvements in high pressure metal vapour discharge lamp
IPC: H05B41/19
Filed: 1964-08-13
Abstract: 1,070,374. Metal-vapour lamps. GENERAL ELECTRIC CO. Aug. 13, 1964 [Sept. 4, 1963], No. 33058/64. Heading H1D. In order to prevent failure of a mercury discharge lamp, resulting from electrolytic decomposition of a metal halide, such as sodium iodide, which is contained within the lamp, the starting electrode is electrically connected to the adjacent main electrode during normal operation. In one form a discharge lamp1 comprises a vitreous outer jacket 2 enclosing a quartz arc tube 12 having main thermionic electrodes 13, 14 and a starting electrode 15, an ionizable filling in the tube 12 comprising mercury, a metal halide and an inert starting gas, a starting resistor 33 between the starting electrode and main electrode 14, and a thermal switch, comprising a bi-metal strip 35, attached to the lead 16 of the second main electrode 13. When starting, the full voltage is developed between the starting electrode 15 and main electrode 13 but when the lamp becomes heated the free end of the strip 35 moves across so that a molybdenum contact 36 engages the lead 18 of the starting electrode, so that the two electrodes 13, 15 are at the same potential. With the above arrangement there is, during running, a continual slight loss through the starting resistor, as it is then connected across the main electrodes. This disadvantage is avoided, according to a second embodiment, wherein the bi-metal strip is arranged to form a change-over switch by means of which, when starting, the starting electrode is connected through the starting resistor to the upper electrode but, during normal running, it is disconnected therefrom and connected to the lower main electrode.

Title: Presser foot for leather sewing machines with curved oscillating needle
IPC: D05B15/04
Filed: 1922-12-05
Abstract: 198,296. Ehresmann, A., and Streibel, L. Dec. 5, 1922. Sewing-machines; presser-bars with periodic control.-In a leather-sewing-machine having a curved needle, the presser-foot is applied to the work before the operation of the needle by a lever actuated by a spring-rotated spiral cam engaging a roller on the lever, so that the pressure of the presser-foot is uniform irrespective of the thickness of the work. The needle a is mounted in a holder pivoted on a shaft c and is reciprocated by a link f connected to a crank e on a shaft d. Arms g carrying the presser foot i are connected together by a plate h forming a guide for the needle. A lever l rigid with the hub of one of the arms carries a roller m entering a spiral cam p on a disc n provided with a ratchet-wheel q and having a hub r in which is a spring tending to turn the ratchet-wheel and spiral in a counter-clockwise direction. A ratchet-bar w mounted so as to engage the teeth of the wheel q is guided by a fixed pin x, entering a slot inclined to the axis of the bar, and has a forked extremity embracing the shaft d. A projection z on the crank e engages a projection y on the bar w in each revolution of the shaft d and causes the retraction of the bar and rotation of the spiral-cam. At a certain point the inclination of the slot causes the ratchet-bar to leave the teeth of the wheel q so that the spiral is then reversed rotated by the spring, the ratchet-bar being returned after release from the projection z by a spring v. The cam p may also be rotated by hand.

Title: Improvements in angle modulated carrier wave receivers
IPC: H03G11/06
Filed: 1945-12-10
Abstract: 614,329. Frequency and phase modulation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Dec. 10, 1945, No. 33277. Convention date, Dec. 9, 1944. [Class 40 (v)] To avoid interference by noise and other amplitude-modulation effects in a frequency or phase modulation receiver, a peak limiter is inserted in the circuit following the demodulator. As shown in Fig. 1, the limiter usually provided between the I.F. amplifier 4 and the discriminator 5 is omitted, and peak limiters 18, 19 are inserted on each branch of the balanced output from the detectors 11, 12. The discriminator may operate as described in Specification 489,094, the output from each load resistance 13, 14 being passed through double-diode limiters 18, 19 to the audio network connected at 27<1>. Each doublediode functions in the manner described in Specification 13071/45 (as open to public inspection under Sect. 91), and has its two anodes connected together and biassed by the D.C. voltage at a tapping 24 smoothed by a filter 25, 29. The audio output at the cathode of each detector 11 is applied through a condenser 16 to the cathode 20 of the first diode. So long as the audio voltage is less than the bias on the anodes, the audio signal passes through the diodes to the output 27<1>. If however, the audio voltage exceeds this value in the positive sense the first diode is blocked. If in the negative sense, current flows in the resistance 23, the anode bias falls and the second diode is blocked. The taps 24, 39 are set so that the wanted FM signal passes freely, whilst excess voltages due to noise components are blocked. The setting does not require adjustment for different strength of the incoming wave. In the modification shown in Fig. 3, the peak limiters comprise double-triode valves 42, 4 mutually coupled by cathode resistances 44, 441. For each branch of the balanced circuit, the grid of the first triode is tapped on the output resistor 40 of the detector 11, and the grid of the second is earthed. The first anode is connected directly to battery B+, and the second anode through the audio output load 47 to B+. For negative swings at the tap 40<1>, limitation is effected at the first grid, whilst for positive swings, the cathodes are driven positive and limitation occurs in the second valve. De-emphasis of the higher notes in the audio output is produced by the shunt condensers 51. In a further modification, Fig. 4 (not shown), a limiter precedes the discriminator 5<1>, and the output from the detectors is taken across both load resistors 13, 14 in series, only a single peak limiter 42 being provided. U.S.A. Specification 2,276,565 also is referred to.

Rods and bars.-Molten metal is poured into a long channel, of any desired section, through or in front of a short cover, the channel member having movement relative to the cover and pourer. The channel-member may be straight and formed of blocks A, which are connected together, carried by wheels D<1>, and advanced by rack and pinion E. The cover may comprise hollow blocks K or recessed blocks K<11>, Fig. 2, with closing plates H and packing K<1>, and is pressed against the blocks A by springs L and screws I. Both channel- and cover-members are cooled internally or externally or both. The metal is introduced through a lined funnel M, Fig. 1, and in starting and is retained at the other end by a plug of metal, fireclay &c. The channel-member moves at such a speed that the metal is sufficiently solidified to be removed by a stripper N, over a roller bed 0, and be cut by flying shears. In a modification one or more channels are formed in an interchangeable rim a, Fig. 5, secured by teeth c and plates d to a rotary member b and cooled by water-jets o, Fig. 6. The cover members k, Fig. 5, screws i, &c. are arranged to be easily swung aside for changing the rim for one of another section if desired. In another modification the channel is spiral and the members have a relative spiral movement. The plug used when starting is preferably shaped as shown at e to facilitate stripping and if of clay &c., may have holes into which molten metal runs. The solidified metal may be consolidated in the channel by a roller or the stripped metal may be compressed or modified in section by passing between rolls.
